.My inventionrelates to cylinders of multigraphing machines, and more particularly .to the Vmounting of the ink-ribbons thereof, and has for its object to provide a simple attachment for holding and guiding the ribbon from lateral departure and crowding tendencies. Y t Y l A4 further object of the invention is to so design the novel attachment that it does not interfere with the vital-featuresor operation of the cylinder or Vthe ribbon.

f A still furtherobject of the invention is to Yso design the novel attachment that it may be quickly mountedor removedwithout undueeilort or Skill.

'With the above objects in view and any others that may suggest-themselves from the specification and claims to follow, a better understanding of the invention may be had by reference to the accompanying drawing, 1n which Y' Fig. l is a'front view of a typical multi graphing cylinder, showing my attachment in place; A

Fig. 2 is a partial cross section, on an enlarged scale, taken on the line 2-2 of Fig. l;

Fig. 3 is an edge view of one of vthe attachmentunits not in use;

Fig. 4 isa plan view OfcFig. V3 o-n an enlarged'scale, and media-lly broken away; and Y Figs. 5, 6,' and 7, are, respectively, sections on' the lines 5 5, 6 6 and 7-7 of Fig. 4.

1 Referring specificallyrto the drawing, v10 denotes the shaft and 11 the ends of a typical multigraph cylinder, 12 indicating the partcylindrical type form therefor, and 13 one pair of stay rods spacing the cylinder ends.

In multigraph cylinders, the ink-ribbon M leads from one spool over the type form and back to be `wound on a companion spool, but asA the travel of the ribbon in the Zone ofl the spools is `not pertinent to my invention, I have not shown the spools or -those parts of the ribbon immediately in connection therewith. However, in passing over the form, kthe ribbon frequently has a tendency to shift Y sidewise whereby to crowd orfwrinkle some of its portions and even depart materially from the course of its travel. Obviously, this action interferes with the smooth Operation -and freely inside the' tongues-"16 thereof.,

of theimultigraph, causing faultyprinting and damage to the ribbon. A In order to overcome the abovedifliculties,

I have designed the novel-attachment in two companion units l5. Each of these is ya strip of spring steel having'a straight course for the'most part, as indicated in Fi ".13, ,andV being deflected at Vboth ends as in icatedl at 15a. One end is turned in with a hook 15b, `while the other end is struck up with an arch 1.50 and continued with* a doubled terminal 15d. Upon the center of the strp'is mounted a slightly spaced tonguevl, and similar portions ofthe strip, all the tongues opening towardl one side vof the strip. ."The tongues maybe riveted to the strip as indi cated atl?) or otherwise connected thereto;

or they may be made integrally withfthe.n

tonguesfl'aare mounted On the deflected,.

tom-and the tongues 16 are designed to have l their openings on the sides facing the ribbon.

In applying the novel guiding attachmentY to the form l2, the units l5 thereof aregirst hooked on the lower stayrod 13 as clearlyl shown in Fig.`2 and drawn up and over the form to closely engage the' periphery thereof, and Venable the `arches 150 to `be Y sprung over the upper stay rod 13,- the fingers using the terminal 15d as ahold .for the manipulation of .theunits` The tension of the latter as well asthe calculated length thereof will .be such as to effect a snug and 50 v permanent wrapping of the attachment uponY the forni, .The lateral spacingiof the.. form Y units will be such asto, permitvthe ribbon tobe laid with its side edges over .theI unitsl Thus, the latter, which are Vthree fin number and may even bel more, will prevent therri'b- I bon from working vsidewise during its travel' and retain the same in proper condition" during the operation 'offthe]cylinder'."1;Itmay'.A

be added that the` firm` connectionffof fthe "um t i 1 fftachment virtuallyan integral part of the latter, Vso Athat the guiding` units and i tongues 16 may bevrelied upon to `hold the same positionsA at all times.

It is obvious .that the novel attachment is Y y "adaptedto be Wrapped over the `type form` y i of utmost simplicity, and being normally in practically straight form-as suggested in 10-`FiggY i3-,may be compactly packed, stored or mailed, AAlso, it is very easy to remove the attachmentfrcm they cylinder yWhen the rib- Y J LA guide bon to'be changed, it only vbeing necessary to snap the arch 150 off the corresponding stay rod lbyl drawing on the terminals 15d. Finally, it is easily seen that the attachment may be reversed relative to either ofthe stay rodsl, as either end may bev applied to a selected stay rrod Without prejudice to theuse- I claim mentsfcarried by the strips toV check the lat- Y 'Xeral deviation of the ribbon during itsV travel.
